Companies can now “print” some products locally, obviating the need for trade. But for hearing aids, the economic shakeup has turned out different thus far. Caroline Freund and Michele Ruta (World Bank) join to discuss their new research examining the many ways that introduction of a transformative technology impacted global trade and consumer access to one important example of a 3D-printed product.

Useful for undergrad students to see how innovation affects trade.
Hi Soumaya and Chad,
I teach at freshman class on Globalization at George Washington University.
I'll share this podcast on 3D printing with my students to prepare for our class on global trade.
I like that you gave some background on economic development concepts and then told the 3D hearing aid story one piece at a time.
Weaving a narrative that pairs theories with real outcomes helps students to understand and retain the big ideas.
Keep 'em coming.
